At the same time, as deductibles rise you've got more people becoming price sensitive to anything priced below the deductible.
Which is a nice way of saying people will think twice about going to the doctor.
I was always for higher co-pays.
But I don't like the way deductibles work now.
To many are letting things go because they will pay for full price for visits they should be making.
You've got co-pays and deductibles backwards. A copay is a flat fee for going, it doesn't send any price signals to the consumer. It's basically just a small barrier to going (do you want to go bad enough that paying the flat fee is worth it?), it doesn't help you decide
where to go.
A deductible, on the other hand, can.
Imagine three providers in your city offering the same service, but pricing it very differently (which is what actually happens in cities all across the country). You have a $500 deductible.
[TABLE="class: grid, width: 500"][TBODY][TR][TD]
Provider A[/TD][TD]
Provider B[/TD][TD]
Provider C[/TD][/TR]
[TR][TD]Procedure Price[/TD][TD]$1,200[/TD][TD]$3,400[/TD][TD]$5,000[/TD][/TR]
[TR][TD]Your share[/TD][TD]
$500[/TD][TD]
$500[/TD][TD]
$500[/TD][/TR][/TBODY][/TABLE]
In this case, it doesn't matter which provider you see when it comes to price because you're not exposed to the actual price of the service.
Indeed, if you were actually shown this information by your insurer in advance while deciding where to get the procedure, you might even be pulled toward the highest priced provider. If you're like most people, you probably assume that Provider C is the highest quality provider (they likely have high name recognition and a well-known reputation to go with the market clout that allowed them to secure that higher price). In the absence of quality information, people tend to equate price with quality in the health care market. Even though the evidence suggests that's not quite how things work.
But let's say your deductible was higher and this is your situation:
[TABLE="class: grid, width: 500"][TBODY][TR][TD]
Provider A[/TD][TD]
Provider B[/TD][TD]
Provider C[/TD][/TR]
[TR][TD]Procedure Price[/TD][TD]$1,200[/TD][TD]$3,400[/TD][TD]$5,000[/TD][/TR]
[TR][TD]Your share[/TD][TD]
$1,200[/TD][TD]
$3,400[/TD][TD]
$4,100[/TD][/TR][/TBODY][/TABLE]
Now the answer to the question of where to get the service may have changed because you're more exposed to the price.
There are only so many ways to put downward pressure on Provider C's prices--deductibles are the option that does it by letting the consumer decide whether that higher price is worth it.
The potential downsides are that 1) people need to have disposable income for the "skin in the game" concept to work, and 2) as you point out, they may not have the information or know how to assess the risks well enough to weigh whether it's worth it to get care in the first place. Doing it this way assumes a lot of the consumer.
I've tried to digest your data in the past, but I don't have the same set of references you do.
That would be the point of explaining it in more depth.
